.NET querying Aspnetusers instead of Custom AuthUser and Yet AspNetUser does not Exist - asp.net

Question

I write a custom IdentityUser which is AuthUser.
public class AuthUser : IdentityUser
{
public int StudentsId { get; set; }
public virtual Students StudentProfile { get; set; }
public int InstructorId { get; set; }
public virtual Instructor InstructorProfile { get; set; }
public bool IsStudent { get; set; }
public bool IsInstructor { get; set; }
}
The context is okay as you can see
public class LmsContext : IdentityDbContext<AuthUser> //DbContext
{
}
The startup.cs is all setup
services.AddDbContext<LmsContext>(options =>
options.UseSqlServer(
Configuration.GetConnectionString("UCIPrimarySchool"))
);
services.AddDefaultIdentity<AuthUser>(options => options.SignIn.RequireConfirmedAccount = true)
.AddEntityFrameworkStores<LmsContext>();
services.AddControllersWithViews();
services.AddRazorPages();
But when I try to login I get the following error.
An unhandled exception occurred while processing the request.
SqlException: Invalid object name 'AspNetUsers'.
Microsoft.Data.SqlClient.SqlCommand+<>c.<ExecuteDbDataReaderAsync>b__169_0(Task<SqlDataReader> result)
Why is is not querying the extended AuthUser but instead goes for the none existing table AspNetUsers?

Answer 1

First, you should clarify your relationship and then migrations and updated the database correctly.
Change your AuthUser like this:
public class AuthUser : IdentityUser
{
public virtual Students StudentProfile { get; set; }
public virtual Instructor InstructorProfile { get; set; }
public bool IsStudent { get; set; }
public bool IsInstructor { get; set; }
}
In your Context:
public DbSet<Students> Students { get; set; }
public DbSet<Instructor> Instructor { get; set; }
Migration and update:
After successfully updating the database, you need to change your View/Shared/_LoginPartial code:
#inject SignInManager<IdentityUser> SignInManager
#inject UserManager<IdentityUser> UserManager
to
#inject SignInManager<AuthUser> SignInManager
#inject UserManager<AuthUser> UserManager
Then
Select your LmsContext Add
Then start your app,and login.
